Meanwhile, farmers looking to avoid herbicides often have to combat weeds with tillage, which causes erosion. With all of the tradeoffs of different management systems, which one should growers use? To answer that question, researchers from the USDA Agricultural Research Service compared nutrient and sediment loss from no-till, conventional tillage, and reduced-input rotation watersheds in a study published online today in Soil Science Society of America Journal.http://phys.org/news290185074.html
EarthTue, 11 Jun 2013 15:58:02 EDTnews290185074New protocol recommendations for measuring soil organic carbon sequestrationIncreased levels of greenhouse gases, particularly carbon dioxide (CO2), have been associated with the burning of fossil fuels, deforestation, cultivation of grasslands, drainage of the land, and land use changes. Concerns about long-term shifts in climate patterns have led scientists to measure soil organic carbon (SOC) in agricultural landscapes and to develop methods to evaluate how changes in tillage practices affect atmospheric carbon sequestration. University of Illinois professor of soil science Kenneth Olson has used data collected over a 20-year period at Dixon Springs, Ill., to develop a new protocol for more accurately measuring the carbon removed from the atmosphere and subsequently sequestered in the soil as SOC.http://phys.org/news278937189.html

However, meeting the demands of a fuel-driven society may require utilizing all biofuel sources including agricultural crop residues.http://phys.org/news215955856.html

This fact prompted the Basque Institute for Agricultural Research and Development - Neiker-Tecnalia - to design a series of research projects in order to evaluate alternative agricultural practices, as a function of their capacity to combine the productivity of crops with the health of the soil. http://phys.org/news167657289.html
